ABS (Acrylonitrile Butadiene Styrene) is a commonly used 3D printer material. Best used for making durable parts that withstands higher temperatures. ABS plastic is less brittle and more ductile than PLA. It can also be post-processed with acetone to provide a glossy finish. When 3D printing with ABS filament, a heated printing surface is recommended, as ABS plastic will contract when cooled, leading to warped parts.
